This run uses noclip as the level in itself is physically impossible. back then they would not really care about it and just assume a wave could get through a dumb gap etc.
Kingdom of Miracalis was generally quite a hated level back in the 2.0 era of impossible levels. It was considered too hard even for those times, so after showing half of the level and getting a bad response GD Miracle decided to spite them and make the second half of the level even harder.
This run does include the invisible gravity portals, gravity orbs in the last half which toshdeluxe removed in his so called ’unnerfed’ showcase.
This level did not take 96 hours to bot.
